Abstract: After obtaining the predictions, a six-channel heatmap was reconstructed, with each point representing the classification result of a patch. For each point, the final class was determined by selecting the channel with the maximum probability.These heatmaps were then used to generate contours corresponding to each category, for which both the area and the mean probability were recorded, as shown in Figure 2. Finally, based on these values, appropriate formulas were applied to calculate the confidence level of the WSI-level classification for each class individually.In all datasets analysed, the number of male patients greatly exceeded the number of female patients, with a male-to-female ratio of nearly 4:1. This distribution follows the well-known trend that bladder cancer occurs much more frequently in men. The NMIBC category includes stages Ta and T1, while MIBC includes lesions from T2 onwards. Approximately 70% of the cases were classified as NMIBC and approximately 30% as MIBC, proportions similar to those reported in the literature. It was also observed that high-grade tumours were more numerous than low-grade tumours.
